How to Use Trade-Up Contracts Without Losing Bank

Trade-up contracts only make sense when you control costs, floats, and target outputs—otherwise you’re lighting skins on fire. Use this workflow to turn low-float fillers into profitable covert skins.

Step 1: Plan the contract

Input grade	Output grade	Example
Mil-Spec	Restricted	Budget backups
Restricted	Classified	Profit sweet spot
Classified	Covert	High-risk/high-reward

Pick cases/collections with limited outcomes so you’re not gambling on dozens of low-value skins.

Step 2: Calculate expected value

1. List every possible output skin and its Price Checker average.
2. Divide 100% by number of outcomes to get probabilities (if evenly split).
3. Multiply each price by its probability.
4. Subtract total input cost.

Example: 4 outcomes averaging $35 with $20 input cost → EV = ($35 × 25% × 4) − $20 = $15.

Step 3: Float control

• Average float of outputs = (Σ(input float × rarity weight)) / 10.
• For low-float targets (e.g., <0.12 AK Ice Coaled), use FT fillers below 0.15.
• Track floats in your spreadsheet before purchasing; use CSFloat sorting.

Step 4: Cost control

Input	Target float	Max price
6x Night Terror FT 0.16	0.16	$4.70 each
4x M4A1-S Basilisk MW 0.10	0.10	$11.00 each
Total		$62.20

If EV < $10, reconsider—fees and time might kill profits.

Step 5: Execute safely

1. Triple-check skins selected in contract window.
2. Screenshot the input list before submitting.
3. Record output float + price immediately.
4. List winner on the market or add to your holdings tab.

Post-contract workflow

• Update spreadsheet with outcome, profit/loss, float.
• Share results in trusted Discord/Reddit threads to build rep.
• Recycle failed outputs via /cs2-skins-under-10 flips so losses don’t snowball.

Frequently asked questions

Can I guarantee profit? Only if expected value is positive and you stick to the plan. RNG still exists.

What about StatTrak? Most trade-up calculators ignore StatTrak; avoid mixing ST and non-ST.

How many contracts per week? Start with 1–2 while tracking results. Scale once you have repeatable success.

Should I use third-party calculators? Yes for double-checking, but verify data yourself via Price Checker.

Buy or sell verdict

• Buy: Input skins only when they fit your float/price criteria.
• Hold: Successful outputs if long-term catalysts exist (case removal, pro usage).
• Sell: Misses quickly to recycle capital—don’t hoard mediocre skins out of pride.

Trade-ups are just math with skins attached. Keep the Price Checker Tool open, cross-check /top-rising-skins for catalysts, and use your spreadsheet to enforce discipline. With clear EV, you’ll know when to press submit—and when to walk away.
